Jim Carrey stars as Carl Allen, a guy whose life is going nowhere-the operative word being "no"-until he signs up for a self-help program based on one simple covenant: say yes to everything...and anything. Unleashing the power of "YES" begins to transform Carl's life in amazing and unexpected ways, getting him promoted at work and opening the door to a new romance. But his willingness to embrace every opportunity might just become too much of a good thing.
